Question

if x is equal to A Y is equal to b is a solution for the system of equation x minus Y is equal to 2 and X + Y is equal to 4 find the value of a and b​

Answer 1

Answer:

Step-by-step explanation:

x = A and y = B

x - y = 2

x + y = 4

x  = 2 + y

putting x  = 2 + y in x + y = 4 we get:

x + y = 4;  2 + y + y = 4; y = 1

y = 1, y = B therefore, B = 1

putting the value of y in x + y = 4 we get:

x + 1 = 4; x = 3; x = A; A = 3

A = 3, B = 1 Answer
